Dont waste your time on this. The last update has made the product worthless-you cant download the update and it just hangs up anyway.
If they fix the update it might be worth it–I got it to replace paper maps while driving up and down the east coast. It was ok, but not nearly as detailed as paper maps. Its mostly a waste of money for anyone with a map app or a Garmin.
